Problems solved by technology

If a terminal serviced by a base station travels into a shadow area, the terminal cannot provide normal service because of the low power level of the signal received from the base station.
However, even when the wireless communication system adopts a multi-antenna scheme to increase the capacity and the data rate, the signal relayed by the repeater cannot increase the data capacity because the repeater still uses a single antenna for communications with the terminals and another single antenna for communications with the base station.

Embodiment Construction

[0025]The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0026]Exemplary embodiments of the present invention provide a technique for supporting a relay service using a multi-antenna in a wireless communication system. In particular, a repeater including a multi-antenna detects a signal received by the multi-antenna and relays the signal based on the orthogonality of a transverse wave and a longitu...

Abstract

An apparatus and a method for supporting a relay service using at least two antennas in a wireless communication system are provided. The apparatus includes at least two antennas, each of the at least two antennas for receiving a signal, at least two factor generators, each of the at least two factor generators for generating a factor used for removing at least one polarization component other than a select polarization component from a signal, at least two filters, each of the at least two filters for filtering at least one polarization component other than a select polarization component from the signal received by one of the at least two antennas using a factor generated by one of the at least two factor generators, and at least two signal detectors, each of the at least two signal detectors for detecting a signal for the select polarization component filtered by one of the at least two filters.

Description

PRIORITY[0001]This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed in the Korean Intellectual Property Office on Dec. 28, 2006 and assigned Ser. No. 2006-136282, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention The present invention relates generally to an apparatus and a method for a repeater in a wireless communication system. More particularly, the present invention relates to an apparatus and a method for a repeater using a multi-antenna in a wireless communication system.[0003]2. Description of the Related Art[0004]As the wireless communications market has grown, wireless communication systems have evolved to provide multimedia services. When providing multimedia services, wireless communication systems transmit large amounts of data at a high data rate. In an effort to more efficiently utilize the limited frequency resources, a multi-antenna scheme (e.g., M...
